What Is Bitcoin SV (BSV)? How It Works and How It Differs From Bitcoin
Bitcoin SV (BSV) is a blockchain and cryptocurrency that split from Bitcoin Cash in November 2018. It focuses on large blocks, low transaction fees, and processing payments and application data directly on its blockchain.
The approach has a clear trade-off: larger blocks can accommodate more activity, but processing, transmitting, and storing them requires more resources. Understanding that balance helps explain why BSV follows a different path from Bitcoin—and what that means for people using the network.
What Is Bitcoin SV (BSV)?
Bitcoin SV is an independent Layer 1 blockchain whose native cryptocurrency is BSV. “SV” stands for “Satoshi Vision,” the project’s stated interpretation of Bitcoin’s original design.
The name reflects its supporters’ goal of building a system for peer-to-peer electronic cash and applications that record data on-chain. Their priorities include expanding block capacity and using Bitcoin Script to support programmable transactions. Claims that BSV represents the “original Bitcoin” express the project’s position rather than an agreed conclusion across the Bitcoin community.
The network and its coin serve different roles. The blockchain records transactions, while BSV transfers value and pays network fees. Applications can also use the network to create digital items, record data, and enforce spending conditions.
Although BSV shares part of its history with Bitcoin and Bitcoin Cash, BSV, BTC, and BCH are separate assets. Each has its own network, market price, and service support. A wallet or exchange that accepts BTC does not automatically accept BSV.
Why Was Bitcoin SV Created?
Bitcoin SV emerged from a disagreement within Bitcoin Cash over block capacity, transaction rules, and the network’s direction. The dispute resulted in a chain split on November 15, 2018.
BSV’s origins involve two separate forks:
- August 2017: Bitcoin Cash split from Bitcoin, increasing block capacity to accommodate more transactions directly on-chain
- November 2018: Bitcoin Cash split again, producing the separate BCH and BSV networks
Both sides of the second split already supported larger blocks. Their disagreement extended to which protocol changes to adopt and how aggressively to expand capacity.
The Bitcoin ABC implementation introduced changes to transaction ordering and scripting. The competing Bitcoin SV implementation, developed by nChain, rejected those changes and supported increasing the block size limit from 32 MB to 128 MB.
That 128 MB figure describes BSV’s early configuration, not its current permanent limit. Subsequent upgrades expanded its approach to scaling, including the Genesis upgrade in 2020.
The split also explains why BSV shares Bitcoin’s early transaction history without being interchangeable with BTC or BCH. After their respective splits, the networks continued recording transactions under different rules.
BSV became a separate network in 2018, but its inherited blockchain history reaches back to Bitcoin’s genesis block from January 3, 2009. That block includes the famous newspaper headline about a second bailout for banks. The shared starting point explains the networks’ common ancestry; it does not make today’s BTC and BSV interchangeable.
How Does Bitcoin SV Work?
Bitcoin SV uses proof-of-work mining to add blocks of transactions to its blockchain. Its UTXO model tracks spendable outputs, while scripts define the conditions required to spend them.
A typical payment moves through four stages:
- Your wallet creates and signs a transaction that spends existing outputs and specifies the recipients
- Network nodes check that the transaction follows their validation rules, including authorization to spend the outputs
- Miners assemble transactions into candidate blocks and compete to find a valid proof of work using SHA-256 hashing
- A successful miner broadcasts a block, which other nodes verify before building on it
UTXO stands for unspent transaction output. Spending an output consumes it entirely and creates new outputs for the recipient and, where needed, change returned to your wallet. The wallet handles this process behind the balance you see.
BSV targets an average block interval of approximately 10 minutes. Individual blocks can arrive sooner or later, and additional confirmations accumulate as subsequent blocks are mined.
An app may display a payment almost immediately after broadcast. That quick response is different from confirmation in a mined block. Larger blocks increase transaction capacity; they do not automatically shorten the block interval or remove the risks of accepting an unconfirmed payment.
Bitcoin SV vs Bitcoin vs Bitcoin Cash
Bitcoin, Bitcoin Cash, and Bitcoin SV share an early history but operate as separate networks with different scaling strategies, rules, and native coins.
Their most useful comparison is how they accommodate activity and what that requires from network participants.
Bitcoin’s capacity is measured using block weight, which accounts for transaction data differently after SegWit. Describing today’s network simply as having “1 MB blocks” misses that distinction. Bitcoin Cash introduced its adaptive block size limit in 2024.
All three use SHA-256 proof-of-work mining, but that does not give them equal security. Each network depends on the computing power committed to its own chain, its participants, and its rules.
For users, compatibility matters just as much as capacity. Check that the receiving service supports the specific asset and network. Similar names or familiar-looking addresses do not make BTC, BCH, and BSV interchangeable.
How Bitcoin SV Scales: Large Blocks and Teranode
BSV pursues higher transaction capacity through larger blocks and node software designed to distribute processing across multiple servers. The practical limits still depend on infrastructure and operator settings.
What “Unbounded” Scaling Means
Following the Genesis upgrade in 2020, BSV removed its fixed consensus block size cap. Operators configure the sizes they will mine and accept.
That creates room for larger blocks, but processing them requires sufficient memory, storage, computing power, and bandwidth. BSV’s own node documentation describes how inadequate resources or restrictive settings can prevent a node from downloading and processing blocks.
More capacity can accommodate additional activity and support low fees. It also increases the resources needed to operate the infrastructure as usage grows.
What Teranode’s Test Results Show
Teranode separates tasks such as transaction validation and block assembly into components that can run across multiple servers. This allows operators to expand processing resources beyond a single machine.
BSV Association announced its first public release in October 2025. According to the release announcement, trials exceeded 1 million transactions per second on a globally distributed test network over two weeks.
That figure describes a reported test result. It does not establish that BSV’s mainnet continuously processes one million transactions per second or that applications generate that level of demand.
When evaluating performance, distinguish tested capacity from actual network activity. Transaction counts also need context: data operations, automated application activity, and payments can all contribute to the total.
What Is Bitcoin SV Used For?
Bitcoin SV supports payments, data recording, digital assets, and applications that use programmable transactions. Its emphasis on low fees makes small, frequent operations a central part of its intended use.
Examples include:
- Micropayments: Small tips, in-app payments, or charges for individual pieces of content
- Data records: Recording document fingerprints, timestamps, or application events for later verification
- Digital assets: Creating and transferring tokens, collectibles, and game items
- Programmable transactions: Using Bitcoin Script to define conditions for releasing or spending funds
For a concrete example, HandCash Items uses the 1Sat Ordinals protocol on BSV to create, manage, and trade digital items. Developers can also build smart contracts with tools such as sCrypt, which compiles contract code into Bitcoin Script.
Data applications require an important distinction. Recording a document’s cryptographic fingerprint can help someone check whether their copy matches the recorded version. It does not establish that the document’s contents are true, that its author owns the underlying rights, or that the information came from a trustworthy source.
Applications also need to consider what they publish. Transaction records are public, so sensitive information requires careful handling before it reaches the blockchain.
The BSV Coin: Supply, Mining, and Fees
BSV is the network’s native coin, used to transfer value and pay transaction fees. Its issuance follows a mining schedule with a maximum supply of approximately 21 million coins.
Supply and Mining Rewards
One BSV divides into 100 million satoshis, allowing transactions to use small fractions of a coin.
A miner’s block reward has two components: newly issued coins, called the block subsidy, and fees from transactions included in the block.
The subsidy halves every 210,000 blocks, approximately every four years. The April 2024 halving reduced it to 3.125 BSV per block, excluding transaction fees. That reward applies to a block, not to each transaction it contains.
How BSV Transaction Fees Work
Network fees depend largely on a transaction’s data size and the fee policies accepted by miners. They are not normally calculated as a percentage of the amount transferred.
A transaction combining many inputs or carrying additional data can therefore cost more than a simpler payment. Exchange withdrawal charges, purchase fees, and application charges may apply separately.
As the subsidy declines, transaction fees are intended to provide a growing share of miners’ revenue. Low fees make individual operations inexpensive, but sustaining that model requires sufficient transaction demand.
Neither low fees nor limited supply guarantees a higher BSV price. Market value also depends on demand, liquidity, access to services, and confidence in the network.
High transaction counts do not necessarily produce high fee revenue. BSV block 972295, dated October 23, 2026, contained 301,537 transactions but collected approximately 0.0674 BSV in fees. Including the 3.125 BSV subsidy, fees represented about 2.1% of the miner’s total reward. This single-block example illustrates why transaction volume and fee revenue need to be assessed separately as subsidies decline.
Bitcoin SV’s Network Rules and Digital Asset Recovery
BSV’s Network Access Rules provide for directives that can require participating nodes to freeze specified coins, reassign frozen coins, or invalidate particular blocks under defined conditions.
The BSV Association issues these directives through the network’s Alert System. Its published rules specify the events that can justify action, including certain breaches of the rules and qualifying legal decisions. The Association cannot issue a directive without a qualifying event under those rules.
The practical effects differ:
- Freezing: Restricts spending of specified unspent transaction outputs
- Reassignment: Changes control of coins that have been frozen
- Block invalidation: Directs nodes to reject specified blocks
Digital Asset Recovery is intended to support recovery through this framework. The Association’s legal FAQ explains that it may act on qualifying court orders or arbitration decisions, while not resolving the underlying ownership dispute itself.
For users, this adds a layer of governance beyond ordinary transaction signing. Holding your own private keys does not exempt your coins from the network’s rules.
Recovery should not be treated as an automatic refund or a replacement for wallet backups. Reassigning coins does not recover a missing private key, and a claim does not guarantee that funds will be returned.
What Are the Main Risks of Bitcoin SV?
BSV carries market, mining, infrastructure, and governance risks. Its large transaction capacity does not by itself establish strong security, widespread adoption, or reliable access to trading services.
Several factors deserve attention:
- Mining security: Sharing Bitcoin’s hashing algorithm does not give BSV access to Bitcoin’s security budget; resilience depends on the hash power securing BSV and how it is distributed
- Infrastructure demands: Processing large blocks requires resources, which can raise the cost of operating nodes and influence who can participate
- Price and liquidity: BSV can fluctuate sharply, while limited liquidity on a particular venue can increase spreads and make larger trades harder to execute at the expected price
- Service availability: Exchanges and wallets make independent support decisions, and deposits or withdrawals may be restricted even when price information remains visible
For example, Coinbase ended BSV support on January 9, 2024. Its notice explains that remaining customer balances were subsequently liquidated and converted into stablecoins. This illustrates why checking current support matters before transferring funds.
BSV’s history also includes Craig Wright’s claim to be Satoshi Nakamoto. In 2024, the High Court of England and Wales found that Wright was not Satoshi, did not author the Bitcoin white paper, and did not create Bitcoin’s original software.
That ruling is relevant to the project’s history and reputation. Evaluating the network still requires a separate assessment of its software, rules, actual use, and available services.
